    I'm currently in Philippines replacing my rotating mast. The previous mast did NOT have a teflon female socket. It came with a grease point.

    The new mast, a 19 meter Proctor, has a stainless steel ball and Teflon female socket. There is no grease point. This mast was once installed and I can see that the old owner greased the socket.

    My conclusion is that this was a bad idea. The grease helped attract dirt and I see a little damage to the Teflon female socket. Further, there is no way to apply new or more grease without lifting the mast off the deck a few inches.

    Therefore, my conclusion is no grease. Anyone have thoughts otherwise?

    Dont know. Perhaps ask Proctor

    Normally you dont grease plastic bearings. Dry teflon spray is what is recommended for delrin ball bearings.

    No grease.
